Hello, I am having problems with bumblebee, on my installation of Mint 14. Previously, everything worked exactly as it should. I had bumblebee, as well as primus, and they worked well. (I do some GPU programming) However, bumblebee wouldn't start on boot, so I had to start it with

$ optirun glxgears[ 4494.795263] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.[ 4494.795330] [ERROR]Could not connect to bumblebee daemon - is it running?

It claims no video card exists. I have however, not changed my drivers at all from when it worked. I have tried multiple reinstalls of bumblebee, bumblebee-nvidia, my linux headers, but nothing seems to have any impact. Any ideas?

Well, it actually works sort of OK for me (starting the daemon). It has to be done at each system startup (adding the command to Startup Applications didn't help, can't be arsed to make a bash script), and my laptop is never completely silent as it was before, but I'm able to reach the same low CPU temperature (ca. 47 degrees with the daemon activated, ca. 58 degrees without). The temperature drop must indicate that starting the daemon means you switch to integrated graphics.

Thank you for this thread. That’s all I can say. You most definitely have made this forum into something special. You clearly know what you are doing, you’ve covered so many bases. Thanks!

I had the problem too with the upgrade to 3.1[ 408.406586] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.[ 408.406665] [ERROR]Could not connect to bumblebee daemon - is it running?I found this solution that has got the optirun glxspheres running fine again.http://stackoverflow.com/questions/1178 ... er-upgrade
